Yeah, I thought Blue Terror was apt for Singing Bell Strike, since it will essentially remove a creature of your choice for 1C but has a restriction (nonartifact nonblack for terror, pay
to get it back for one use for SBS)Generic answer to OP:
My advice? If you really want to win, stay away from Jeskai and Sultai: their clan-specific stuff is pretty bad. I did a big analysis of faction pack value, but most people didn't care for it. Long story short, Mardu has the best rares/faction specifics narrowly over Temur and Abzan. I think the Abzan have the best mechanic for power level but Mardu share 2/3 of their colors so why not try for Butcher of the Horde/Zurgo Helmsmasher and still run the vast majority of your outlast? Temur's pretty solid too but doesn't overlap well with the other power clans so you'll have fewer options, and of course taking Abzan themselves sets you up for the most nuts outlast BS
However, no matter which you pick it's just 1/6 rares and not even a full 1/6 of your pool, really, and without guaranteed promos you're dicing it anyway. Zurgo may laugh in Narset's face, but Narset laughs at the guy who pulled an Ascendency from his Mardu pack (... Or maybe she doesn't. Bad example, Narset is really terrible in limited. But the jeskai theme deck rare is still probably better than an ascendency, so there.), so there's that. And if your five non-seeded packs give you a powerful pool that doesn't support your chosen faction you may play something else entirely, that's just how it works.
Me? I'm going Jeskai. Their rares are terrible, but I love their art and flavor and I think that their trickery theme will be really fun to play with, even if it's not going to win me a ton of games. Plus, blue and white have really strong commons so that's good and if my white's not so great I could flux into Temur and take advantage of the depth of green. I'll still get totally blown out by Butchers, Surraks, Zurgos, and so forth, but I'm comfortable with that. If there was more on the line than the little crack-of-sunday-dawn prerelease I'm going to, maybe I'd take my own advice and pick Mardu instead but I'm too much a Johnny/Vorthos and not enough a Spike to do it when the difference is probably about 2 packs, tops, between me pioliting a UP Jeskai build and me crushing my enemies, seeing then driven before me, and hearing the lamentations of their women behind Mardu.
